You should see a gain from porting and polishing any heads. Of course it depends on how well the job is done. You definitely want to do the intake ports as well though because you're only going to flow as best as the most constricting part of the intake. While you're doing that, put some better springs on as well as 1.6 roller rockers.

you would need to open up the rest of the intake system( port plenum and base, install large tube runners) and also install a freer flowing exhaust
